Marcello, as far as I can tell (not that my informal judgment should have much evidential weight) those things concentrate probability mass some but still radically underdetermine manipulation strategies, being consistent with a wide range of psychologies. Unless evolution is very strongly convergent in some relevant way (not a negligible probability), a wide variety of psychologies can arise even among oxygen-breathing trichromats on a planet of X size in 3+1 spacetime (and so on).

And, yes, I did mean to include other possible universes. Unless there's only one consistent TOE, I doubt it could deduce chemistry, although the rest of the list is fairly plausible.
